Range of transmission

by AndrewSoh on Sat Jan 29, 2011 2:15 pm

Just a question guys, what is the range of transmission u get on your zigbees? The furthest I've gotten is 5~6 meters in open space. Once there's a wall or something the signal just goes. The RSSI pin doesn't light up anymore after that.

Typically about 300' with no obstructions. Are the modules totally in the open. No enclosure or anything?

One is in the open, the other is in a kill-a-watt.

Could be due to the limited power available in the Kill-A-Watt.

Oooh, so you mean the Kill-A-Watt is not providing enough power to the transmitter chip? Hmmm. I've gotta check this out. Thx. BTW I'm using a Kill-A-Watt EZ, but it's the UK model as I'm living in Malaysia.

It is possible. One way to find out is to take the module out of the Kill-A-Watt and connect it to an FTDI/serial cable or an Arduino and see if your range improves.

The chip antennas hate anything ontop of them like a wire etc. That was killing the range on something I was doing when I had it boxed up, open it and it came right. Troubleshooting nightmare.
